Consuming web service in console application

Introduction

Here I am creating a simple web service and using it in a console application. Using a web service in a console application is similar to using a web service in window application. At first, we create a web service. Follow the given steps.

• Create new project
• Select ASP.NET Empty Web Application
• Give name to your project and click ok button
• Go to Solution Explorer and right click at your project
• Select Add New Item and select Web Service application
• Give it name and click ok button 

Now replace the code in the .asmx.cs page with the following code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
 
namespace myproject
{
    /// <summary>
    /// Summary description for MyService
    /// </summary>
    [WebService(Namespace = "example.abc/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    // [System.Web.Script.Services.ScriptService]
    public class MyService : System.Web.Services.WebService
    { 
        [WebMethod(Description="show simple message")]
        public string show()
        {
            return "My Web Service Application";
        }
        [WebMethod(Description = "show datetime")]
        public string showdate()
        {
            return DateTime.Now.ToLongDateString();
        }
        [WebMethod(Description = "addition of two int")]
        public int add(int a,int b)
        {
            return a + b;
        }  
    }
}

Run the application

Output window:

 

Now, create a new project and take Console Application.  Add the service reference. For doing this, follow the given steps.

• Go to Solution Explorer and right click at your application.
  
  

 

• Click Add Service Reference. A new window will be open.

 

• Click the "Advanced" button. A new window will be open.

      

• Again click the "Add Web Reference" button. Again a new window will be open.

 

• Copy the URL of your running service application and paste to it at URL( As given in above figure) and click the "Go" button.
  

   

• Set the service reference name. The default name is "localhost". Now click the "Add Reference" button.
  

Now the service has been added in your console application. Write the following code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MyApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            myservicereference.MyService obj = new myservicereference.MyService();
            Console.WriteLine(" Calling Web Methods");
            Console.WriteLine("---------------------");
            Console.WriteLine("\n Calling show Method");
            Console.WriteLine("  "+obj.show());
            Console.WriteLine("\n\n"+" Calling showdate Method ");
            Console.WriteLine("  "+obj.showdate());
            Console.WriteLine("\n Calling add Method ");
            Console.Write("  Enter First Number:");
            int a = Convert.ToInt32(Console.ReadLine());
            Console.Write("  Enter Second Number:");
            int b = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("\n  Addition is:" + obj.add(a, b).ToString());
            Console.ReadLine();
        }
    }
}
 
Press Ctrl+f5 to run the code.

Output:

 

 Enter first and second number. Then press "enter".

Output:
